Description

Technical Field

[0001] The utility model relates to deburring of steel billets after cutting in a steelmaking continuous casting area, in particular to a deburring mechanism for steel billet continuous casting. Background Art

[0002] In the steelmaking continuous casting cutting area, after the billet comes out of the continuous casting machine, it needs to be cut to size at the cutting machine, and then transported to the subsequent processing link through the conveyor line. When the billet is cut in the cutting machine area, a large amount of high temperature will be generated, causing scrap iron to fall to the ground. At the same time, there is often cutting residue (cross-section burrs and iron nodules) left below the cut end of the billet; therefore, the conveying device is generally not arranged below the cutting machine area; that is, the front and rear conveyor lines need to reserve a gap in the cutting machine area.

[0003] However, due to the large span of the cutting machine area and the high temperature of the billet after cutting, the billet head will bend downward. If the cutting residue left at the lower end of the cut end face of the billet after cutting is not removed in time, the serious bending phenomenon after cutting will also cause the billet to top the billet; in this way, some large burrs will often be pressed into the steel when they are sent to the rolling mill for rolling, and the pressing of the burrs will cause the steel to produce scrap, which will cause single-stream accidents in the production process and produce scrap after rolling.

DETAILED DESCRIPTION

[0029] In order to better understand the technical solution of the present utility model, a specific implementation plan is provided as follows; and the following scheme is only for illustration.

[0030] like Figure 1-8 As shown, the embodiment includes a base 501; a guide rail is provided on the base 501, and a slide unit 516 is slidably connected to the guide rail; and a guide rail dust cover 503 for shielding the guide rail is provided on the base 501; the setting of the dust cover can effectively prevent the steel billet from dropping debris due to high-temperature cutting during cutting, which pollutes the guide rail and affects the sliding of the slide unit 516; and the dust cover is located between the guide rail and the slide unit 516 and does not take up space.

[0031] A receiving roller 512 is rotatably mounted on the carriage unit 516, and the receiving roller 512 is arranged at one end of the carriage unit 516 facing the continuous casting machine outlet 1. A deburring roller 513 is rotatably mounted on the carriage unit 516 and on one side of the receiving roller 512; an oil cylinder 506 is also arranged on the base 501 for driving the carriage unit 516 to slide forward and backward along the guide rail. The guide rail is arranged along the length direction of the base 501, and the base 501 and the guide rail dust cover 503 are both made of high temperature resistant material. Specifically, the deburring mechanism is arranged below the cutting machine 6 and between the outlet conveyor line 2 and the receiving conveyor line 3.

[0032] Preferred solution 1: the carriage unit 516 includes a concave frame, which includes a left vertical plate 509, a right vertical plate 510, and a bottom plate respectively connected to the two vertical plates, and the three together constitute the concave frame; wherein the bottom plate is slidably connected to the guide rail through at least one set of L-shaped brackets; the receiving roller 512 and the deburring roller 513 are both rotatably connected between the left and right vertical plates, and when the carriage unit 516 slides to the bottom of the cut steel billet, the deburring roller 513 and the receiving roller 512 are both in contact with the bottom of the steel billet; the steel billet passes between the left and right vertical plates 510 and does not contact the left and right vertical plates 510. That is, there is no mechanical interference between them.

[0033] There are two guide rails, and each set of L-shaped brackets includes two L-shaped frames mirrored relative to the center line of the bottom surface of the concave frame, and each L-shaped frame corresponds to a guide rail; and the vertical portion of each L-shaped frame is fixedly connected to the bottom of the concave frame, and the horizontal portion of each L-shaped frame is provided with a slider end (i.e., the guide slider 502), and is slidably connected to the corresponding guide rail through the slider end. Specifically, the horizontal portion of the L-shaped frame extends toward the center line of the bottom plate, which can save more space and achieve a reasonable layout. The deburring roller 513 and the material receiving roller 512 are located at the left end of the concave frame. In addition to the two rollers, the concave frame has a storage space, and the storage space allows part of the material receiving conveyor line 3 to enter the storage space when the slide unit 516 travels to the end of the base 501B. In this way, the floor space of the entire machine can be further reduced, achieving the purpose of saving space.

[0034] Preferred solution 2: Multiple rows of alloy cutter heads 515 are arranged at intervals on the outer surface of the deburring roller 513, and multiple alloy cutter heads 515 are arranged at intervals in each row of alloy cutter heads 515; when deburring, the alloy cutter heads 515 are in contact with the bottom of the steel billet. After cutting, the burrs of the steel billet are concentrated under the steel billet, so the deburring roller 513 can effectively remove most of the burrs of the steel billet.

[0035] Preferred solution three: a chain transmission unit 514 is provided on the carriage unit 516 for driving the deburring roller 513 to rotate, and the chain transmission unit 514 includes a driving sprocket, a driven sprocket, and a chain connected to the two sprockets; wherein the driving sprocket is driven to rotate by the motor 511; and the driven sprocket is sleeved outside the roller shaft of the deburring roller 513. Specifically, the motor 511 rotates to drive the driving chain to rotate, and through the chain transmission, the driven sprocket rotates to drive the roller shaft of the deburring roller 513 to rotate, and the deburring roller 513 rotates relative to the carriage unit 516.

[0036] Preferred solution 4: A rear vertical plate 504 is provided at the rear end of the base 501 to prevent the slide unit 516 from slipping off the rail. The oil cylinder 506 is arranged horizontally, and the cylinder seat of the oil cylinder is fixed on the rear vertical plate 504. The cylinder rod of the oil cylinder is connected to the slide unit 516, driving the slide unit 516 to move forward and backward along the guide rail. The cylinder rod of the oil cylinder 506 is connected to the slide unit 516 through the front vertical plate 505. After the cylinder rod passes through the front vertical plate 505, the end that passes out is locked and fixed by the locking nut 507. Among them, the front vertical plate 505 is fixedly connected to the bottom of the bottom plate of the slide unit 516 and extends downward for a certain distance. However, because the height of the vertical part of the L-shaped bracket is higher than the height of the front vertical plate 505, there is space under the bottom plate for accommodating the front vertical plate 505 and the oil cylinder, and the front vertical plate 505, the oil cylinder, etc. are located above the guide rail dust cover 503 and do not contact each other. Reasonable space utilization.

[0037] Example 1: When in use, the base 501 and the guide rail of the deburring mechanism are arranged below the cutting area. Before the deburring mechanism cuts the steel billet, the deburring roller 513, the receiving roller 512 and the L-shaped vertical plate slide to the end B of the guide rail and exit the cutting area. At this time, the high-temperature scrap steel and the like dropped after the cutting machine 6 operates fall onto the high-temperature resistant guide rail dust cover 503, and will not damage the guide rail and the roller.

[0038] After the cutting machine 6 completes the cutting, the billet is transported forward by the exit conveyor belt, and the deburring mechanism starts the oil cylinder to drive the roller to move along the guide rail to the bottom of the end face of the billet (that is, end A), and the receiving roller 512 is used to straighten the sinking head of the billet, and the deburring roller 513 is used to remove the burrs on the end face of the billet.

[0039] Finally, the steel billet reaches the material receiving conveyor line 3, and a process is completed. The rollers of the deburring mechanism return to the B end (i.e., the origin) along the guide rail. Because there is space between the left vertical plate 509 and the right vertical plate 510 and the right side of the deburring roller 513 to accommodate part of the material receiving conveyor line 3 (i.e., there is space between the left and right vertical plates of the carriage unit 516), the backward movement of the vertical plate will not cause mechanical interference (i.e., collision, etc.) to the material receiving conveyor line 3, and will not affect the operation of the material receiving conveyor line 3.

[0040] During the whole process, there is no need to change the structure and movement process of the original cutting machine 6, the outlet conveyor line 2, and the inlet conveyor line; it is only necessary for the cutting machine 6 to transmit the signal to the deburring mechanism after completing the cutting.

[0041] Embodiment 2, with reference to the accompanying drawings, illustrates the working process and working mode of the deburring mechanism of the utility model:

[0042] 1. After the billet is transported out from the continuous casting machine outlet 1 through the outlet conveyor line 2, it reaches the cutting area of ​​the cutting machine 6.

[0043] 2. The cutting machine 6 cuts the steel billet according to a set program. Generally, the steel billet is cut into lengths ranging from 6 to 12 meters.

[0044] 3. After the billet is cut, it continues to be transported forward. Burrs and iron nodules are generated on the cross section of the billet after cutting. At this time, since there is no conveyor line support under the cutting machine 6, the billet continues to be transported forward and will sink and bend.

[0045] 4. To avoid this situation, at this time, the deburring mechanism is started, the oil cylinder is actuated, the oil cylinder rod is extended, and the receiving roller 512 is moved to the left as a whole, so that the deburring mechanism as a whole fills the area below the cutting machine 6.

[0046] 5. Since the receiving roller 512 is at the same height as the outlet conveyor line 2, the steel billet continues to be conveyed forward through the receiving roller 512 as it continues to be conveyed forward.

[0047] 6. Start the motor 511, which drives the deburring roller 513 to rotate counterclockwise through the chain transmission unit 514.

[0048] 7. Alloy blades 515 are evenly distributed on the upper surface of the deburring roller 513 .

[0049] 8. When the end of the steel billet passes through the deburring roller 513, the deburring roller 513 will cut off all the excess burrs and iron nodules below the cross section of the steel billet. (Since the top of the contracting cutter head of the deburring roller 513 is at the same height as the top of the receiving roller 512, the alloy cutter head 515 will not damage the main body of the steel billet, and will only remove the excess part of the lower end of the steel billet that is higher than the main body of the steel billet).

[0050] 9. Optimal design: After the end of the steel billet passes through the deburring roller 513, the motor 511 stops moving and the deburring roller 513 stops working.

[0051] 10. When the billet reaches the receiving conveyor line 3, the oil cylinder of the deburring mechanism is started, the oil cylinder rod is retracted, and the oil cylinder drives the receiving roller 512 to the rightmost end, and the deburring mechanism completes the deburring work.

[0052] 11. When the next time the steel billet needs to be cut by the cutting machine 6, the deburring mechanism continues to repeat the above actions.

[0053] The utility model solves the problem that the burrs on the rear end face of the existing steel billet cutting cannot be removed, proposes a steel billet continuous casting deburring mechanism, which realizes overall movement through a hydraulic cylinder, realizes offline and online deburring device, and realizes reasonable avoidance with the cutting machine.

[0054] The utility model can remove burrs on the end surface of the steel billet by driving the deburring roller to rotate through a motor. When the burrs pass through the alloy cutter head, the chips of the alloy cutter head fall off, thereby realizing efficient deburring.

[0055] The deburring mechanism of the utility model has reasonable and exquisite design, is convenient to use and replace, and has low manufacturing cost.

[0056] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some or all of the technical features thereof may be replaced by equivalents.
